User-defined routes missing from generated path/URL helper RBI files after upgrading to Rails 8

We’ve recently upgraded our application to Rails 8. After the upgrade, we noticed that our user-defined routes are no longer present in the RBI files generated by Tapioca for path and URL helpers.

Specifically, the following files appear to be affected:

• sorbet/rbi/dsl/generated_path_helpers_module.rbi
• sorbet/rbi/dsl/generated_url_helpers_module.rbi

It seems that only routes defined by Rails itself are still present in these files, while all our custom routes defined in config/routes.rb are missing. This was working correctly before the Rails 8 upgrade.

Rails version: 8.0.2
Tapioca version: 0.17.1
Ruby version: 3.4.3

Start with config/routes.rb and the DSL generation command shown in the generated RBI headers: bin/tapioca dsl GeneratedPathHelpersModule and GeneratedUrlHelpersModule. Compare the custom routes with the contents of sorbet/rbi/dsl/generated_path_helpers_module.rbi and sorbet/rbi/dsl/generated_url_helpers_module.rbi after generation. Done means user-defined path and URL helpers appear in both generated files on Rails 8.
